As David said, "This is yet another marker for me that the book is a REAL thing, and will really be in print soon..." I second that emotion!

If the book isn't physically being printed, as I write this, it's either on the printer's queue (or, perhaps, already run off) in China. The street date is October 1st, but copies may surface before then, depending on when the book is printed and how long it takes copies to arrive, via the proverbial slow boat from China, to our consumer shores.
